First off, Skyliner and Original Sin are for the most part, the exact same tracks featured on the vinyl, but Imagination seems to have a few little changes to it, the most prominent being the synth line at the very beginning, which plays throughout the whole song, unlike the original which only features it near the end (if I remember correctly).
The second big difference is Soundwall, which is almost entirely different from the EP version. In fact, I didn't even notice it was Soundwall until I checked the credits in the back of the instruction booklet. I actually can't decide which version I like better, they are equally nasty in comparison.
The third is the inclusion of a 5th track not found on the vinyl at all, titled Kaleidascope. I think it's a unique sounding track, and more softer sounding than Dom usually is.
