Preheat oven to 350 degrees F . Spray a 9x5-inch loaf pan with nonstick spray and line with parchment paper; set aside.
In medium-large bowl, combine flour, pumpkin pie spice, cinnamon, baking soda, baking powder and salt; whisk together to combine. Transfer combined ingredients onto large piece of parchment or wax paper; set aside.
Place eggs in same medium-large bowl and whisk well.
Add pumpkin and whisk until smooth. Add oil, white and brown sugars and the vanilla. Mix until well combined.
Using edges of paper, pour flour mixture into bowl, stirring until the flour has disappeared and no large lumps remain.
Transfer batter to prepared pan, smoothing the top.
Bake 55-65 minutes, checking after 40-45 minutes. If the top seems to be getting too brown, tent the top loosely with foil to prevent overbrowning.
Return to the oven and finish baking, until a toothpick inserted into the center of the loaf comes out clean.
Cool in pan 5 minutes, then lift out by parchment paper and transfer to wire rack to cook completely before slicing.
When cool, drizzle with maple glaze.
