Preheat the oven to 350 degrees. Grease a loaf pan and set aside. In a mixing bowl, combine pumpkin, eggs, sugar, and vanilla extract. Add flour, baking soda, baking powder, and pumpkin pie spice and mix until well combined. Fold in chips, saving a few to sprinkle on top of the batter. Bake for 45-50 minutes and allow to cool completely before cutting.
