In a medium sized mixing bowl, whisk together flour, cinnamon, cardamom, cloves, baking soda, baking powder, and salt, then set aside.
Next, in a small bowl, mix the egg substitute together following the package directions, set aside to thicken.
Place brown sugar and the vegan margarine into a food processor.
Add the egg substitute to the food processor and pulse, scraping down the sides as needed.
Continue by adding the flour mixture and pulse, process until no dry flour remains but the mixture remains crumbly, scraping the sides down as needed.
Transfer the dough to a bowl and knead gently until smooth.
Prepare 2 baking sheets with parchment paper, this paper will also be used to roll out the dough.
Place one of the parchment sheets on to the counter, place the dough onto the paper.
Take the second parchment sheet and place it on top of the dough.
Roll out the dough with a rolling pin.
Try to keep the dough in the shape of a rectangle, cutting down the sides as you roll out the dough.
Continue rolling out the dough evenly to about 3/8 inch thickness.
Transfer the dough onto a baking sheet and place into the refrigerator for no less than 90 minutes.
After 90 minutes, remove the baking sheet from the refrigerator, and preheat the oven to 300°F.
Transfer the chilled dough to the counter and gently peel off the top parchment paper.
Place the peeled off layer of parchment paper onto a a baking sheet. This is where you will place the cookies once cut.
With a pizza cutter or a pastry wheel, cut lengthwise strips about 1 1/4 inches wide.
Next cut each strip crosswise about 3 inches long.
Transfer the cookies to the parchment lined sheets, spacing the cookies at least 1/2 inch apart.
Place one baking sheet in the oven at a time for 15 minutes, rotate the baking sheet, and bake for another 15 minutes.
The cookies will bake for a total of 30 to 32 minutes, and will be light and evenly browned.
Remove from the oven and let the cookies completely cool on the baking sheet.
Store in a air tight container, at room temperature for up to 3 weeks, or freeze to enjoy at a later day.
