Alignment
You can break someone's alignment by manipulating their spine. This can be done via the head, shoulders, or hips.
Control the spine with the Head
Control the head with a crossface or chin strap. If you ever get to head and arm control from on top (e.g. after a Snap Down), get a chin strap. The chin strap allows for exceptional spinal control and allows you to easily break your opponent's alignment

Limbs facing your opponent
Another key part of alignment is pointing your limbs at your opponent. A frame is much more powerful if your limb is pointing at your opponent (in alignment). It is much harder to push someone over if their legs are pointing at you.
