Preheat the oven to 425 degrees and line a baking sheet with parchment paper.
Add the refried beans, taco seasoning and water to a pot over medium heat - you only need enough water to thin the beans out so they are smooth; omit if they seem smooth without it. Cook for a couple of minutes or until the beans are warmed through. Remove from the heat.
Warm the tortillas (see notes). Grab 1 tortilla and spray both sides with some oil. Spread some beans on the tortilla and top with some cheese. Fold over and press down gently so the taco stays in place. Repeat with the remaining ingredients and place on the prepared baking sheet. Place in the oven for 10 minutes, flip and cook for another 5-10 minutes, or until crispy.
While the tacos are cooking, add the vegan mayo, chipotle & 1/2 a lime juiced to a bowl and mix to combine. In a separate bowl combine the yellow onion, 1/2 the cilantro and the remaining lime juice. Sprinkle with salt & pepper and mix to combine. Set aside.
Serve the tacos with the cilantro/onion mixture, the chipotle sauce, the remaining cilantro and more lime wedges.

Notes
Always check the refried bean can ingredients to make sure there aren't any animal products.
I like to warm my tortillas by wrapping them in a damp paper towel and putting them in the microwave for 30-60 seconds.
Warming the tortillas should keep the tortillas from splitting, but if they do split, they will still taste delicious!
Some of the filling may spread out while they are baking. Just gently press it back in before serving.
For air fryer: cook the tacos in the air fryer at 370 for 8 minutes. Flip and cook for another 5-8 minutes.
