CHOCOLATE CHIPS. Seriously. I started putting chocolate chips in my pancakes just a small while back, but I can't imagine eating a pancake without them in it already. Woooooooo!
Then I slather them with butter. Lots of butter, I cannot get enough of that stuff. Then I put a little flavored syrup. :D
As for waffles, I don't really have much experience with them, as I don't have them very often. When I do, though, I just give them the good old syrup-and-butter treatment.
