I believe the rules allow for the DM to declare that someone is making use of improved cover at a whim. There's plenty of situations where I would allow people improved cover without needing to explicitly lay down.
I'd say that any form of "changing how my cover works" would occur as part of a move action (that is: it's free if you move, and it takes a move action if you wish to remain stationary). I'd also say it wears off when you take another action.
This loose interpretation will lead to more opportunities for stealth in combat, and more options for dealing with ranged attackers.
Crouching would naturally fall in as part of this.
