Make the seitan: In a mixing bowl, whisk the vital wheat gluten, nutritional yeast, and spices.
Add the 3/4 cup veggie broth and soy sauce to the vital wheat gluten mixture and mix until combined. Knead for a couple minutes until firm and stretchy.
Bring the remaining 2 1/2 cups broth and water to a boil in a large, tall saucepan.
Form the seitan into a long, oval-like patty and place into the boiling broth mixture.
Bring the mixture to a light simmer and cook for about an hour, flipping halfway through.
Once it has about doubled, remove it from the broth and let it cool.
Whisk together the flour mixture ingredients in one bowl and the panko mixture ingredients in another.
Once the seitan has cooled, slice the seitan into long ~1/2 inch thick pieces that resemble tenders.
Either pour oil in a deep fryer to the fill line or fill a large saucepan about 1 inch high with canola oil and heat to 350°F.
For each piece of seitan, coat in the flour mixture* then the panko mixture and place in the hot oil.
Cook on each side for 2-3 minutes until crispy.
Make the dipping sauce by mixing together all the ingredients.
Enjoy the warm tenders dipped in the sauce!
Notes
*The tenders should have be covered in a thin coat of the flour mixture. If the mixture seems too thick, add a little extra water.
