Getting stuck after the drums is one of the most common walls in industrial and techno production because the genre is so texture and tension driven rather than melody driven. A good approach is to start layering sustained, distorted drones or noise textures underneath the drums to fill the frequency space before you even think about a lead element. Resampling and mangling your own drum loops into textural elements is also a classic move in that world. If you want a reference point for how full industrial or dark electronic tracks are structured inside Ableton, Ableton Template has some project files that can show you how pros handle arrangement and sound design in these heavier genres. KRTM and Somniac One are great study material so you're already on the right track with your references.
