If I were trying to approximate it, I would start with a drone or an obstinate, a moderate tempo, a simple harmony structure (one or two interesting chords), and some interesting sounds. Maybe think in terms of modes, rather than scales...
It's kind of ambient and sparse, which leaves lots of room for odd-sounding synth effects to kind of fly in from left field.
Don't think too hard; pick a simple repeating note pattern and see what you can lay over it.
