This process involves me making a video with the lesson material I want the student to practice. The student will record a video of themselves playing the lesson material using a phone, computer, or something similar and send it to me once they have practiced it enough and feel confident with it. (It need not be anything elaborate.) Since all I would need to watch a video on YouTube is a link, it works really well. I'll give the student some pointers, additional lesson material, or both to work on after I watch the video.
