Any chance you can get the Pleasure or Destiny Domains? Destiny has a lot going for it, but mostly I speak of Choose Destiny at 9th level, while Pleasure has some nice stuff, in particular it's level 7 spell - which can outright win encounters. Sky has a very nice 8th level spell, too.
Be sure to get all of those with Substitute Domain or a Domain Staff of some sort.
Destiny = Races of Destiny
Pleasure = Book of Exalted Deeds
Sky = Races of the Wild
Oh, and you can always choose the Divine Magician ACF and just pick from the Wizard spell-list. 8th level has Veil of Undeath/Mystic Shield (!), 7th has Ironguard... Mystic Shield is worth the ACF alone.
