I think a lot of people have given the same answer I'd give (as many as you want, but don't force them upon the players), so I thought I'd talk a slightly different tact.
The one aspect that drove home to me that I needed to write my own pantheons was the existence of the racial gods for all races except human. That felt wrong to me, until I realized that my solution was to take the deities who were unlisted racially (Torm, Sune, Bane, Pelor, ect ect ect) and make them the human gods while building out pantheons for each of the different races.
That worked for me and I've been slowly trying to figure out what religion, the gods, and worship look like for each of these races. It feels like a naturally extension of the world to me.
The other solution is to make a single pantheon worshipped by all races. So, Moradin would simply be the god of the forge instead of the god of dwarves. If you wanted to include racial deities as well, I'd make sure to include an equivalent number of human deities to keep the balance sheet.
