Preheat the oven to 350 degrees Fahrenheit.
Add 1/3 cup silken tofu, 1/3 cup cold water, 2 tablespoons lemon juice, 1 tablespoon extra virgin olive oil, 2 1/2 tablespoons soy sauce, 1/4 cup nutritional yeast, 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder, 1/2 teaspoon dried rosemary, and 1/2 teaspoon dried thyme to a blender.
Blend until smooth, then transfer that mixture to a mixing bowl.
Spoon 1 cup vital wheat gluten into a measuring cup (don’t scoop), then add it to the mixing bowl.
Use your hands to mix the ingredients together, then knead for 2-3 minutes.
Divide the dough into four equal pieces, then place them in a 9x13-inch baking dish (or similar size) lined with parchment paper.
Pour 1/3 cup cold water into the corner of the baking dish (not directly on any of the pieces of dough).
Cover the baking dish with an oven-safe lid or aluminum foil, then bake for 45 minutes.
Let the chicken rest for 15 minutes before serving.
Optional finishing touches: brush the chicken with more extra virgin olive oil, sprinkle on finely chopped chives, black pepper, and a squeeze of fresh lemon juice.
