Combine flour, baking powder, baking soda, salt and pumpkin pie spice in a large bowl. Mix together well and make a well in the center. Add eggs, pumpkin puree and vanilla. Stir just until combined.
Preheat a griddle and add batter to the griddle. Heat for 3 minutes on each side or until set.
This batter is thick, so you may have to spread it out a little on the griddle when you pour it on.
