What you recall is probably Arcane Disciple feat in Complete Divine which adds spells from a chosen domain (one of your deity's domains) to your class spell list, but thats for arcane casters.

@Brother Numsie: As Jmobius suggested talk to your DM. There is nothing overpowered in granting Turn Undead to Favored Soul and one domain. glhf
