Preheat the oven to 350 degrees and grease a loaf pan.
In a small bowl, whisk together the egg replacer and 2 tbsp of water. Set aside. In a mixing bowl, add the pumpkin puree, brown sugar, vegetable oil, almond milk and egg replacer. Whisk together until combined.
Add the all-purpose flour, cinnamon, nutmeg, cloves, baking soda, baking powder, and salt to the wet mixture. Stir with a large spoon until just combined. Be careful not to over-mix.
Fold in the chopped walnuts. Pour the mixture into the greased loaf pan and bake for 75 minutes or until a toothpick inserted into the center comes out clean.
Let cool in the pan for 30-45 minutes and then remove the loaf from the pan.
