Clerics can make all sorts of useful items.
On the wondrous item front, you have access to almost all of the buff spells, so that means Periapts of Wisdom, Belts of Giant Str, etc. You can make Pearls of Power to refresh your spells. You can make defensive wondrous items like Amulets of Protection (bonuses to saves a la Resistance or to AC via Deflection through Shield of Faith). Items like the Monk's Belt can also be made by clerics and your party druid will love you for it.
On the armor and weapons side I don't know why you couldn't make simple +X gear (magic weapon spell?) and holy equipment. You might be able to substitute some of your own energy damage spells for the given requirements if necessary.
If you have an allied mage or wizard then you can have them cast the requisite spells while you supply the XP and the feat to make the item. You can also pay an NPC to cast them. You can also use multiclassing to become a mystic theurge and cast them yourself (maybe through a scroll or wand) or just get a half rank in Use Magic Device (if you have decent charisma and wisdom) and rely on scrolls for the spells you don't have access to. Domain spells might prove helpful as well.
