There is no simple explanation for a VOR approach. There are several types and several, steps involved. Here's a very simple VOR approach plate. I'm not going to get into specifics here, because we'll be covering them soon in the Flight School (you're welcome to join in).
To execute a VOR approach safely and realistically... there are a lot of instrument procedures and concepts you'll need to understand. The old "gotta walk before you run" deal
Which also means learning it all in a nice, slow C172, before trying it in a big, fast jet.. That goes for getting lined up with a runway and safely on the ground, too. Ya can't do that in jets before you can do it in a little Cessna (including navigating (no GPS) and doing it all in poor visibility (no auto-pilot).
If you're bound and determined to try instrument approaches in jets, before you can realistically fly a Cessna.. A member (Nav) put this ILS tutorial together.. It's very good..
