Below you'll find a list of the most conventional deities and their regular domains. Classes which receive divine spells should not be more than one alignment step removed from their chosen deity's and both of a priest's domains should match their deity's.
There are rare exceptions to both of these rules. For instance, Mystra allows LN priests and Azuth's Illusion domain (not available here) could be represented as Trickery in certain cases, though trickery is not at the core of his dogma. Ask a DM about the possibilities.
