- In a large bowl, mix vital wheat gluten, nutritional yeast, garlic powder, onion powder, smoked paprika, and salt.
- In a medium bowl, whisk vegetable broth, soy sauce, and tomato paste until smooth. Pour into the dry mix and stir to form a dough.
- Knead dough on a clean surface for 2–3 minutes until elastic and smooth. Shape into a log or small seitan pieces.
- In a large pot, bring 4 cups vegetable broth and 2 tbsp soy sauce to a boil. Reduce to a simmer and gently add seitan.
- Cover and simmer for 45–60 minutes. Longer cook time = firmer texture.
- Remove from broth, let cool, then slice or dice for use.
Optional: Steam instead by wrapping in foil or using a steamer basket over medium heat for 45–60 minutes.
