A number of years back, I tried a number of different tools to try to tether to my smart phone or tablet. To suggest that my success rate was not good; nicely said the hardware / software combinations did not work. Tethering to a laptop running Capture One is my preferred solution (Lightroom connectivity was a bit hit and miss as the connection is not as stable as I would like). That is going to be a bit large and awkward for what you are trying to do.
My Panasonic GX-7 has built-in tethering to a SmartPhone and I have used that occasionally and it also has a tilting screen, so that option works too.
What did work well, albeit a bit expensive, with both my D800 and D810 is using a CamRanger (1st generation) with either a phone or tablet. It does give remote control, which you don't want.
