Preheat oven to 325°F. Grease or line two 8x4 inch loaf pans with parchment paper.
Make the flax eggs by mixing together the flax meal and water in a small bowl and letting it sit for 5 minutes. In a large bowl, whisk together the vegan butter and brown sugar. Beat in the flax eggs, pumpkin puree, and vanilla extract.
In a medium size bowl, whisk together the flour, baking powder, baking soda, cinnamon, cloves, and nutmeg. Add the dry ingredients to the pumpkin mixture and stir with a spatula or wooden spoon until just combined, don't overmix.
Evenly distribute the batter into both of the prepared loaf pans and bake for 60-70 minutes, until toothpick inserted into the center of a loaf comes out clean. Let the loaves cool completely in the tins before removing and slicing. Enjoy!
