the problem is your yamaha mg10/2 is pretty limited.
you will have to look at the "Two Way Communication Mixer to Soundcard AND Soundcard to Mixer with Direct Outs or Inserts "
if you use the INSERTS, the EQ will be bypassed.
There is no real advantage of connecting the soundcard back to the mixer for monitoring. in your case. because your mixer is not meant for this purpose.
if you really want to do it.
Connect your microphone to Channel 1 of your mixer, half-insert a 1/4 inch cable to Channel 1's INSERT. the other end is a RCA that connects to your EMU Audio IN. You can do the same for Channel 2 too. So as to record 2 tracks at one go.
Since your mixer only has 2 INSERTS, you can only do 2 tracks at 1 go. (got other ways but defeats the whole purpose again).
From your Soundcard Audio OUT -> Mixer 2TR IN
