There are probably several ways of doing this, but if you are fine with using a mobile friendly web interface, you could check out
Awesome Miner. The main application where you setup everything is Windows-based, but it also has a build in web interface that can be accessed from a tablet or smart phone.
Please note that the web interface is communicating with Awesome Miner, and Awesome Miner is connecting to the Antminer. There is no direct connection between the smart phone and the miner.
