Start marinating the shiitakes, place the sliced mushrooms in a bowl, and add the soy sauce, maple syrup and liquid smoke to the bowl. Toss the mushrooms in the sauce and let marinate while you make the tofu scramble.
Make the scramble. Squeeze a good amount of the liquid out of the tofu. Then heat the olive oil in a non stick pan. Crumble the tofu into the pan, and start cooking on medium high. Stir constantly and make sure the crumbles are pretty uniform sizes by breaking up with a wooden spoon.
Add the remaining scramble ingredients and stir. Cook for a few more minutes until the tofu is warmed through and starts to brown. Remove from heat.
Next cook your marinated shiitakes, by heating oil in a cast iron pan(preferably), if you don't have cast iron, just a non stick pan. Add the mushrooms to the pan and cook on each side for a minute or two until brown and crisp. Remove from heat.
Roll out your dough, to your desired thickness. Place dough on a prepared pizza stone or pan. Brush with a bit of olive oil. Top with tofu scramble, thinly sliced potatoes(like super thin, maybe 18th of an inch), shiitake bacon, then vegan cheese.
Bake at 450 degrees for 12-17 minutes or until nice and brown and potatoes are cooked through. Top with green onions if desired. Serve immediately!
Notes
Make sure the potatoes are super thin so they get cooked through when the pizza is baked!
