The Prophets may be gods to the Bajorans, but to me they don't meet the criteria of being gods.
To be a god, they need to be the creator of a race, have great powers, and be immortal.
That's how modern Western civilization on Earth tends to define gods. But other cultures have differed. In most polytheistic mythologies, for instance, only one or two gods are attributed with creating humanity, while others play different roles. And in Egyptian mythology, gods could die, although they could also be resurrected (see Osiris).
