here's some examples from my last campaign
i made up a handful of specialty priest prestige classes for my last campaign world. (i was going to do more, but the campaign folded early.)
here's one for a CE god of fire, lightning, and war.
Burning One of Unamash
Unamash of the Shining Spear is the god of war, fire, and lightning. He represents the chaotic destructiveness of both nature and mankind.
Some priests of Unamash focus on the fiery aspects of their god, and become burning ones. These special priests are greatly revered amongst Unamash's worshippers, as they are seen as living vessels of their god's sacred flame.
Burning ones are zealots. Since Unamash is also a war god, many burning ones take their preaching to the front line, engaging the enemies of their god with reckless abandon. All burning ones are active individuals, more prone to acting on events than thinking about them.
Burning ones most often start out as clerics of Unamash. Many have a few levels in fighter or barbarian to increase their fighting ability.
NPC burning ones rarely work together. Usually they can be found working with other worshippers of Unamash, leading by example.

Class Skills: Concentration, Craft, Heal, Intimidate, Knowledge (religion), Profession, Scry, and Spellcraft.
Skill Points: 2 + Int mod.
Class Features
Weapon and Armor Proficiency: Burning ones are proficient with all simple weapons. If the burning one is of at least Medium size, he is also proficient with the longspear. Burning ones are also proficient with light and medium armor, as well as shields.
Additional Domain: At 1st level, the burning one may choose a new domain from among those granted by Unamash. If the burning one does not already have the Fire domain, this must be chosen. If the burning one did not previously have access to domains (if he was not a cleric), then he gains the Fire domain's granted power, and gains one additional divine spell per spell level he is capable of casting. These additional spells must be the Fire domain's spells.
Detect Good: This ability is similar to the Detect Evil ability of Paladins (Player's Handbook, page 42), except that it detects Good alignments.
Smite Good: This ability is similar to the Smite Evil ability of Paladins (Player's Handbook, page 42), except that it works against foes of good alignment only. The burning one may attempt to smite good once per day at 1st level, twice per day at 5th level, and three times per day at 9th level. Use the total of the character's burning one levels and cleric of Unamash levels as the damage modifier.
Spells per Day: A burning one continues the divine spellcasting of his previous class, but more slowly. For every two burning one levels gained, the character gains new spells per day as if he had gained one level of the spellcasting class he belonged to before he became a burning one. He does not gain any other benefit of the level that the character would have normally gained. This essentially means that he adds half his burning one level to the level of his other spellcasting class to determine spells per day and caster level. For example, an 8th level cleric / 4th level burning one has the spellcasting ability of a 10th level cleric.
Fire Resistance: Unamash protects his chosen. Starting at 2nd level, a burning one gains fire resistance. The burning one may ignore the first 3 points of fire damage taken from each attack at 2nd level. This rises to 6 points at 4th level, 9 points at 6th level, 12 points at 8th level, and finally 15 points at 10th level.
Sacred Firefan: This is identical to the Sacred Firefan ability of the Flame Steward (Dragon Magazine #283, page 85).
Burning Aura: Starting at 5th level, a burning one may call down the divine fire of Unamash. Once per day, the burning one may declare he is activating his burning aura. He is then wreathed in flickering red flames for a number of rounds equal to his burning one class level. While the burning aura is active, all melee attacks made by the burning one deal an additional +2d6 fire damage. Likewise, any successful melee attack made on the burning one while the aura is up deals the attacker 1d6 fire damage as he contacts the flames. The burning one and his possessions are completely unharmed by this magical fire.
Sacred Flame Strike: This is identical to the Sacred Flame Strike ability of the Flame Steward (Dragon Magazine #283, page 85).
Sacred Firestorm: This is identical to the Sacred Firestorm ability of the Flame Steward (Dragon Magazine #283, page 85).
for this next prestige class, i had originally wanted to do something Sufi-like for my LN Islamic-style religion. the class ended up being a mixture of divine and arcane magic, and could possibly serve as the specialty priest of a magic god.
Sateti Esoteric
The Esoterics are the smallest and most secretive of the factions of Satet. They believe in the Overgod as an ineffable and aloof deity. The other gods are seen as merely emanations of the true god, separate and yet a part of him. Because of this, Esoterics will sometimes pay homage to them, even if it vexes other Satetis.
Esoterics are also steeped in mystical and arcane traditions. Many Esoteric priests become wizards in an attempt to more fully understand the mysterious powers of the Overgod. Most Esoterics spend time as ascetic monks in Great Satara, to clear their minds of worldly thoughts, to better meditate on the Overgod. These monks are seeking to discover the secret connections between divine and arcane magic.
Most esoterics started out as clerics, and most have learned something of wizardry before joining the order. Much rarer are those who are natural spellcasters, i.e., sorcerers.
NPC esoterics are generally found alone, living as ascetic monks and hermits out in Great Satara. There are some esoteric monasteries dotted throughout Aldehan, Owalan, and even Bahet, but these generally will not accept applicants. They will be directed into the desert, to find the masters who live there.
Hit Die: d4.
Requirements
Alignment: Must be Lawful Neutral, True Neutral, or Lawful Good.
Knowledge (arcana): 8 ranks.
Knowledge (religion): 8 ranks.
Spellcraft: 6 ranks.
Feats: Endurance and Spell Penetration.
Spellcasting: Ability to cast both 1st-level arcane spells and 1st-level divine spells.
Special: The character must travel into Great Satara and seek out an Esoteric mentor. Also, the character must worship the Overgod exclusively, and belong to the Esoteric faction of Satet.

Class Skills: Concentration, Craft, Diplomacy, Heal, Knowledge (arcana), Knowledge (religion), Profession, Scry, and Spellcraft.
Class Features
Weapon and Armor Proficiency: An esoteric is proficient with all simple weapons, but no form of armor.
Bonus Spells: This ability is identical to the Bonus Spells ability of Mystics (Dragon Magazine #274, page 50).
Spontaneous Domain Casting: This ability is similar to the cleric's ability to spontaneously cast healing or harm spells. If the esoteric's divine spellcasting is not from the cleric class, they gain the ability to spontaneously cast healing spells as a cleric. If the esoteric's divine spellcasting is from the cleric class, he gains the additional ability to "lose" a prepared divine spell in order to cast a domain spell of the same level or lower.
Asceticism: By 2nd level, an esoteric has learned to temper his body with rigorous training and meditative exercises. He may go a number of days without food, water, or sleep equal to (2 + Wisdom modifier, minimum 1) x level. For example, a 4th level esoteric with a 15 Wisdom could go without food, water, or sleep for 16 days, or a little over two weeks. This is an extraordinary ability.
Arcane Skill Bonus: The esoteric spends much of his time immersed in study and contemplation of magic. At 3rd level, he gains a +2 competence bonus on all Knowledge (arcana), Spellcraft, and Use Magic Device checks. This bonus increases to +4 at 5th level and +6 at 7th level.
Divine Arcane: By 4th level, esoterics have meditated on the powers of magic to such an extent that they begin to see unity in the ways of divine and arcane magic. The esoteric may now increase his caster level with his divine spells by an amount equal to either his level in the esoteric class or his level in an arcane spellcaster class, whichever is lower. Conversely, he may also increase his caster level with arcane spells by an amount equal to either his level in the esoteric class or his level in a divine spellcaster class, whichever is lower. Note that this is only caster level: the esoteric does not receive more spells per day because of this ability, he merely increases the level-based effects of his spells. For example, a 6th level cleric / 2nd level wizard / 4th level esoteric has an effective cleric caster level of 8th level (6 + 2 from wizard, which is the lower of his wizard and esoteric classes), and an effective wizard caster level of 6th level (2 + 4 from esoteric, which is the lower of his cleric and esoteric classes).
Unrestricted Spontaneous Casting: At 6th level, an esoteric is so in touch with the Overgod that he need not prepare his divine spells ahead of time. All of his divine spellcasting is performed as a sorcerer. Note, however, that if the esoteric has domain spells available from the cleric class, these stay fixed. The slots from domain spells must only be used to cast domain spells.
Insight: At 8th level, an esoteric may commune with the Overgod to gain some insight into a problem at hand. The Insight ability may be used once per day starting at 8th level; this increases to twice a day at 9th level, and three times per day at 10th level. Gaining insight is a move-equivalent action and may be used in combat. When using this ability, the esoteric must state the problem that he wishes to gain Insight on. He then gains a +20 competence bonus to the one next skill check, saving throw, or attack roll that relates to the problem. This is a supernatural ability.
Transcendence: At 10th level, the esoteric has transcended the mundane and become a murshid: a master of the spiritual life. The esoteric is no longer wholly of this world, as a divine emanation of the Overgod has entered his being. The practical effect of this is that the esoteric gains damage reduction 15/+1.
and lastly, again for my Islam-style religion, i wanted to make an assassin prestige class that was less arcane than the DMG assassin, and more based on the way the real assassins behaved: i.e., they were fanatical religious zealots and disdained sneak attacks in favor of wide-open suicidal frontal assaults. this might be appropriate for a prestige class for a lawful murder, death, or vengeance god.
Sateti Holy Slayer
The Holy Slayers are a special order of warrior-priests of Satet, who have learned the ways of the assassin as a means of gaining power. These ruthless and fanatical killers believe that if they kill and die for the Overgod, they will be guaranteed Paradise.
Most holy slayers are either Moralists or Canonists. In either case, they must be willing to sacrifice their life for the order and for their beliefs.
Holy slayers are trained and organized in cells, and operate in secret, both from the outside world and from other cells. Although they have the tacit acceptance of most of the nations of Satet, they believe secrecy to be one more of their arsenal of weapons that gives them power over their enemies.
The victims of holy slayers are usually apostate Satetis, trouble-making polytheists, and the personal enemies of the various Moralist and Canonist priests who employ the slayers.
Most holy slayers started out as rogues or rangers. Fighters or bards are also somewhat common. Rare are the holy slayers who were spellcasters originally, although some of the Moralist priesthood will sometimes hear the call to slay for the Overgod.
NPC holy slayers are generally close-lipped and efficient killers. They are fanatically devoted to their cause, and almost nothing can sway them once they have embarked on a course of action. Holy slayers tend to work in small, discrete cells of about four. These cells are generally under the guidance of a particular priest. There are larger groups of holy slayers; these are usually the training grounds for new recruits.
Hit Die: d6.
Requirements
Alignment: Must be Lawful Evil or Lawful Neutral.
Base Attack Bonus: +4
Hide: 8 ranks.
Move Silently: 8 ranks.
Disguise: 5 ranks.
Knowledge (religion): 3 ranks.
Special: The character must worship the Overgod exclusively, and belong to either the Moralist or Canonist faction of Satet. In addition, he must kill someone at the behest of a Moralist or Canonist priest, for no other reason than to join the Holy Slayers.

Class Features
Weapon and Armor Proficiency: A holy slayer's weapon training focuses on weapons suitable for stealth and quick strikes. Holy slayers are proficient with the dagger, club, light crossbow, dart, sling, sap, short sword, rapier, scimitar, shortbow, kukri, hand crossbow, and the whip. Holy slayers are proficient with light armor, but not shields.
Fervor: At times, a holy slayer's devotion and zeal can overcome him. When he needs to, a holy slayer can work himself into a fanatic fury. While in the grip of fervor, a holy slayer gains phenomenal strength and durability but becomes reckless and less concerned with defending himself. This is similar in all respects to a Barbarian's Rage ability (Player's Handbook, page 25), except the bonues are +4 to Strength, +2 to Constitution, and a +4 morale bonus on Will saves, with a -2 penalty to AC. A holy slayer may enter fervor once per day at 1st level, twice at 3rd level, three times per day at 5th level, four times at 7th level, and five times per day at 9th level. At 9th level, the holy slayer is no longer winded after the bout of fervor has passed. This is an extraordinary ability.
Fanaticism: At 1st level, a holy slayer is immune to fear (magical or otherwise). In addition, he receives a +2 morale bonus against mind-affecting spells or spell-like abilities. This is an extraordinary ability.
Poison Use: This is identical to the Poison Use ability of Assassins (Dungeon Master's Guide, page 30).
Fast Movement: Starting at 2nd level, the holy slayer gains a speed faster than the norm for his race. This is identical to a Barbarian's Fast Movement ability (Player's Handbook, page 25).
Uncanny Dodge: Also starting at 2nd level, the holy slayer gains an extraordinary ability to react to danger before his senses would normally allow him to even be aware of it. This is identical to the Rogue ability of Uncanny Dodge (Player's Handbook, page 48). If the holy slayer receives this ability from another class, the levels stack for determining the bonus.
Precise Strike: At 4th level, the holy slayer gains the extraordinary ability to strike precisely with light piercing weapons. This is identical to the Precise Strike ability of Duelists (Sword and Fist, page 18). At 4th level, the damage bonus is +1d6; this increases to +2d6 at 8th level. Precise Strike cannot be used while under the effects of fervor.
Death Strike: At 6th level, a holy slayer can execute a death strike with a melee attack once per day. The holy slayer must announce his intention to use the Death Strike before he makes his attack roll. If the attack roll is successful, the victim must make a Fortitude saving throw (DC 10 + the holy slayer's class level + Strength modifier) or die immediately. If the saving throw succeeds, the attack still does damage as normal. Death Strike can be used while under the effects of fervor. This is a supernatural ability.
Spells: As early as 1st level, a holy slayer may gain the ability to cast a small number of divine spells. To cast a spell, the holy slayer must have a Wisdom score of at least 10 + the spell's level. Holy slayer bonus spells are based on Wisdom, and saving throws against these spells have a Difficulty Class of 10 + spell level + the holy slayer's Wisdom modifier. When the holy slayer gets 0 spells of a given level, such as 0 1st-level spells at 1st level, the holy slayer gets only bonus spells. A holy slayer has access to any spell on the list below and can freely choose which to prepare, just as a cleric can. A holy slayer prepares and casts spells just as a cleric does, excepting spontaneous casting.
Holy Slayer Spell List: Holy slayers choose their spells from the following list:
1st level -
bane, detect magic, doom, guidance, inflict light wounds, shield of faith.
2nd level -
darkness, death knell, endurance, spider climb, undetectable alignment.
3rd level -
bestow curse, blur, deeper darkness, invisibility, silence.
4th level -
freedom of movement, locate creature, nondetection, poison.
