Add the vital wheat gluten, all purpose flour, nutritional yeast, and all the spices to a bowl and combine. In a food processor or blender add the silken tofu, soy sauce, tomato paste, apple cider vinegar, liquid smoke, and the vegetable broth. Blend until smooth.
Combine the wet mixture in to the dry. Mix with hands until no dry flour is visible. Continue to knead for 1 minute. Roll the seitan in to a short log and wrap it in foil.
Boil half pot of water. Place loaf in a steamer basket and steam for 45 minutes.
Remove from steamer and let cool for about 10 minutes.
Preheat oven to 375F. Then, unwrap and remove from the foil. Score the loaf by slicing diagonal one way then the other way creating squares. Place loaf on to a baking tray and brush with ⅓ of the glaze.
Surround the loaf with largely chopped seasoned vegetables like potatoes, carrots, cauliflower, and onion. Cover tray with foil and bake for 1 hour.
After 1 hour, remove foil and brush with half of the remaining glaze.
Now, this second bake depends on your oven. The loaf should be very firm. If it's still soft, bake for 20-30 more minutes without the foil. If it's firm, bake for 10 more minutes without the foil. Brush the loaf with the remaining glaze.
Thinly slice and serve & enjoy! *I cut mine thick for the photo but I highly recommend cutting them in to thinner slices.
