In a small saucepan, add drained black beans, beer, oregano, garlic powder, paprika, and about 1 teaspoon of salt. Place over low-medium heat and bring to a simmer. Allow to cook about 20 minutes, adding additional beer or chicken broth as needed.
While the beans are cooking, prep the shrimp. Place shrimp into a bowl and add juice of half a lemon, olive oil, black pepper, and 1 teaspoon kosher salt.
Next, microwave the two ears of corn still in their husks for about 2-3 minutes. Set aside.
Next, prep the mole sauce. Add about 1/2 a jar of the mole pipian to a large saucepan over low-medium heat. Add about 1 cup of chicken broth. Stir with wooden spoon until smooth. Cover to keep warm and set aside.
Heat up grill to medium-high heat. Add corn first and cook about 5-10 minutes until slightly charred on all sides. Next - cook shrimp (I recommend using skewers or a grill pan if you are using smaller shrimp so they don't fall through the grates) about 2-3 minutes on each side.
Serve grilled shrimp over mole pipian sauce and top with black beans, charred corn, and chopped cilantro.
