Minimal set of .apk files to enable Google Play
Check the "Barebones" page on the CyanogenMod wiki.

It lists which apks are required for what. So instead of listing minimum apk list, you can just select the required apps for Play. By the way Google Play, Market or Vending are the same things. At a minimum you will will need Vending.apk and MarketUpdater.apk, and possibly GoogleServicesFramework.apk
