In a food processor, combine the chickpeas, miso paste, mushroom powder, garlic powder, vegetable stock, nutritional yeast, tomato paste, liquid smoke, maple syrup, paprika, and olive oil. Process until smooth. If using, add the grated beet for color and pulse until well combined.
Transfer the mixture to a large mixing bowl. Gradually add the vital wheat gluten, stirring with a spatula or your hands, until a dough forms. Knead the dough for five minutes to develop its texture. -If you have a strong food processor that will not burn out, you can do this mixing step right in the food processor, mixing for just 2 minutes.
Shape the dough into a compact loaf and wrap it tightly in foil, ensuring there are no gaps or loose ends.
Place the wrapped loaf in a steamer and steam over medium heat for one hour.
While the loaf is steaming, prepare the maple glaze. In a small saucepan over low heat, melt the vegan butter. Stir in the brown sugar, maple syrup, apple cider vinegar, Dijon mustard, and ground cloves. Simmer for two to three minutes until the glaze thickens slightly, then set aside.
Preheat the oven to 375°F (190°C).
Once the loaf has finished steaming, carefully unwrap it and make shallow, crisscross cuts across the surface of the loaf. Brush the loaf generously without ⅓ of the maple glaze.
Optionally, once glazed, insert whole cloves at the intersections of the cuts.
If you like, you can arrange pineapple rings on top of the loaf, securing them with toothpicks.
Place the loaf on a baking tray and roast in the preheated oven for 20-25 minutes, basting with another ⅓ of the glaze halfway through.
Remove from the oven and allow to rest for ten minutes before drilling with the remaining glaze, and thinly slicing using a serrated knife. Garnish with fresh parsley and sage leaves before serving.
