Transformer balanced devices such as dynamic microphones and passive DI boxes are usually OK with phantom power being present even if they don't need it. Anything that is not definitely transformer balanced should not be connected unless it is explicitly specified to be connected to phantom power.
Your wireless receivers, which, if they have balanced outputs, are almost certainly active balanced, should not be connected to phantom.
But there is a solution: The Yamaha mixer puts phantom only on its Mic (XLR) inputs, not on the Line (1/4 inch TRS) inputs. So, if your receivers have line level outputs, use those and connect using 1/4 inch and you'll be all set. If your receivers offer only mic level output, then the other option you have is to use a 1:1 transformer isolation box such as the ART DTI or Whirlwind ISO-2, connected between the receivers and the mixer. One isolation box can handle two mic channels.
