Preheat your oven to 350°F (175°C).
In a mixing bowl, combine the vital wheat gluten, smoked paprika, garlic powder, and onion powder.
Add the vegetable broth and soy sauce to the dry ingredients and mix until a dough forms.
Knead the dough for a few minutes, then shape it into a rectangle about 1 inch thick.
Place the dough on a baking sheet and bake for 30 minutes.
Remove from the oven, brush with BBQ sauce, and bake for another 15 minutes.
Let cool slightly before slicing and serving.
