It sounds like you are mostly worried about getting good feedback from users when they are using clicks instead of touches. This is an understandable concern as touch experiences can be quite different.
Without shipping touchscreen hardware to users, you will need to find some sort of proxy for the mouse. I wonder if asking the users to touch their screen with one hand while also moving the mouse to the same position could help? Asking users to even just pause and touch the screen to note how that "feels" and what on the interface is obscured could return interesting insights. Record a video of yourself doing these acts to show users how you'd like them to "fake it". Another aspect you might think about simulating is the performance of your hardware. Often small, embedded devices are slower than desktop PC's. Embedded devices often have slower screen refresh times as well. Simulating this could provide useful. I had to do this when prototyping an e-ink interface and found that replicating that strange white/black/white flash you see on the Kindle to be pretty easy and very eye opening.. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
