In a large bowl, combine the dry ingredients. Add the milk, club soda, egg yolk, lemon zest, vanilla, and oil, and beat well.

In a separate bowl, beat the egg whites on high speed until stiff peaks form. Carefully fold the egg whites into the batter.

Lightly spray or wipe a large regular or nonstick skillet with vegetable oil. Place the skillet over medium-high heat; drop the batter into the pan by tablespoonfuls to form 2-inch pancakes, and cook until they are golden brown on both sides.
