Mash the cooked pumpkin with a potato masher in your favorite large bowl. Mix the cream cheese and brown sugar with the mashed pumpkin. Whisk in the eggs one at a time. Add the vanilla, half-and-half, cinnamon, ginger, allspice, and cloves; stir until you have a thin batter. The batter should be slightly thinner than pancake batter. Pour the batter into the pie crusts.
