any suggestions for ways to keep my pancakes from sticking to the pan?

Rub the griddle with a bit of salt just before pouring the batter. Salt in a cheesecloth is a good way to do it.
Non-stick spray, obviously. But a little neutral-flavored oil put on with a paper towel will also work.
Butter or oil in the batter, a skillet hot enough to make a drop of water dance across it (more medium than hot), a swish with an oiled paper towel and not trying to flip the pancake too soon: A pancake will pull itself away from the pan when it's ready and golden.
Heat the pan first then when hot, gently brush on some oil/melted butter
rub a little oil over the pan with kitchen towel. Also, don't fiddle with the pancakes too much, when they are done on one side they should easily lift away from the pan.
