Hi there! Just gave a listen to the song you listed. Unfortunately, there isn't much you can do over this sort of progression due to the nature of the chord progression being used. You are also correct about it being in the key of EB minor. So you could obviously play Eb natural minor or Eb minor pentatonic. Having said that, you could slip in A Phrygian dominant (D Harmonic minor). I would play this only over specific parts of the song i.e when the chords shift to A major or G minor. That'll give you a nice bit of tension outside of the typical diatonic sound.
As far as the original goes, it really depends on the chord progression. Context is everything when it comes to modes. If you want something minor but more upbeat I'd suggest the Dorian mode. Dorian has that haunting minor sound with a bit of hope thanks to the natural 6 interval. Though you'd have to be sure to write your progression to fit accordingly or the Dorian mode won't work. Again context is everything.
A basic example of EB Dorian would be to play an Eb minor7 chord and then move to A Major or Adom7.
Anyways, feel free to reach out anytime and we can discuss more in detail about your original tune as well as what chords/modes are available to you.
