In a food processor, pulse vital wheat gluten, tofu, water, nutritional yeast, onion powder, vegetable broth powder, garlic powder, and salt until the dough forms a ball.
Alternatively, mash tofu with a potato masher, then mix in the rest of the ingredients. Stir in vital wheat gluten to form dough.
Dust a clean surface with vital wheat gluten, then shape dough into 6 ovals, each about 5" x 6".
In a large pot with a steamer basket, bring water to a gentle simmer. Grease the steamer basket and place tenders inside.
Cover and steam for 25 minutes, flipping halfway, until internal temperature reaches at least 160°F (71°C).
Let tenders cool and chill in the fridge for at least 1 hour or up to 3-4 days.
Once chilled, season and cook tenders as desired—pan-fry, grill, bread, or slice for various dishes.
