Traditional pancakes are basically just flour and eggs, so you can tweak the traditional recipe to make it more physique friendly.

1 cup oat flour
2 whole eggs
4 egg whites
1 scoop protein powder
1/4 cup blueberries

Mix above ingredients together and cook in a hot pan or griddle.
Serve with sugar-free syrup.

Play with the ratios of eggs to flour to get your preferred recipe. Too many eggs and too little flour makes the cakes too dense, but if you go too far the other way you will be increasing the carbs and decreasing the protein, and at some point you might as well just eat regular pancakes.
