Add the tofu, vital wheat gluten, nutritional yeast, water, miso paste, onion powder, vegetable broth powder, garlic powder, salt, thyme, and sage to a food processor. Using the S-blade, blend the mixture until it is mixed well and forms a ball in the food processor. If a ball doesn't form then turn it into a ball by hand. *Do not knead the dough as it will make the turkey tough.
