Control phone from tablet when it's playing movies on TV?

[hunterx82]

I am going on a long trip and I have the OTG cable paired with HDMI to watch movies and TV shows from my phone on the TV. One annoying thing is that if I need to pause it or control it in some other way, I have to get up and do it on the phone.

Is there an app that will allow me to control what is playing from my Nexus 7? I am going to post this in that forum as well since there could be different solutions from different audiences.
