Some domains (at least War) should probably give you the cleric BAB.
How does this look?
Water Domain (possible suggestion)
1: Swim Speed equal to 1/2 your base speed.
2: Domain spells and turn and destroy fire creatures.
3: Rebuke and command water creatures.
War Domain (new suggestion)
1: Medium armor proficiency, Weapon proficiency (if necessary)
2: Domain Spells, Heavy armor proficiency, Weapon Focus
3: 3/4 BAB
Protection Domain
1: Iron Will/Lightning Reflexes/Great Fortitude (priest's choice)
2: Spells and Ability
3: Immune to non-magical disease, stablize 50% of the time when unconcious and bleeding instead of 10%.
