How Do I Make an Ground Plane in iRay that Fades into Infinity?

  If I'm understanding what you want to do (that is, have it fade rather than create a horizon line), then that would probably be easiest.

  Fortunately, such a transparency map should be pretty easy.  draw a circle in your graphic editior of choice, then fill with a circular white to black gradient with the start of said gradient being fairly near the end.  make the background also black and you're all set.

  How do I put this in iRay?  Do I load it in the opacity slider?

  In iray, it's 'Cutout Opacity' - but yeah, put it there.

  If you're in 3DL shader (default) then it's just 'Opacity' and it'll get converted at render time.
