Combine the chickpeas, lentils, parsley, cilantro, garlic, jalapeno, olive oil, lemon zest, salt, onion powder, cayenne pepper and cumin in the bowl of your food processor. Pulse until the mixture comes together and is broken down substantially (about 10-12 pulses). Fold in the chickpea flour, and then form the mixture into 8 equal-sized balls. Place them on the prepared baking sheet and place them in the oven. Bake the falafel for 20 minutes and then remove from the oven to cool slightly.
