Heat oven to 325°. Spray your Bundt cake pan with cooking spray.
In a medium bowl, combine flour, baking powder, baking soda, salt, and spices.
In a large bowl, cream the butter, white sugar and brown sugar until light and fluffy. Beat in eggs, one at a time, beating well after each addition. Beat in pumpkin and vanilla.
Slowly beat dry ingredients into wet ingredients. Continue beating on medium speed until smooth and well blended. Pour into the Bundt pan and bake for 55 to 60 minutes, or until a wooden toothpick comes out clean when inserted in center.
Cool for 15 minutes in the pan on a rack; invert onto a serving plate to cool completely. Glaze with the Maple Pecan Glaze (see below).
