Bring 4 cups of veggie broth to a boil in a medium saucepan. Add 1+1 cups of TVP, stir, and remove from heat. Let sit for about 10 minutes until liquid is absorbed and TVP is tender.
Drain and rinse the canned chickpeas. Mash them in a mixing bowl using a food processor or potato masher until mostly smooth with some texture.
Combine the soaked TVP, mashed chickpeas, 3 Tbsp olive oil, 1 cup vegan mayo, 1 Tbsp lemon juice, and all spices (sage, thyme, marjoram, onion powder, garlic powder, salt, and black pepper) in a large mixing bowl. Mix thoroughly.
Add 1 cup white rice flour and 4 Tbsp tapioca starch. Stir until a cohesive dough forms. Add more rice flour if mixture is too wet.
Shape mixture into patties about ½ inch thick using clean hands. Size as preferred.
Place 1 cup panko breadcrumbs in a shallow bowl. Coat each patty gently in breadcrumbs, pressing lightly to adhere.
Heat 4 Tbsp vegetable oil in a large skillet over medium heat. Fry patties 4-5 minutes per side until golden brown and crispy. Drain on paper towel.
