Being on the starting side of the learning curve, I have found the following approach to be quite effective. I learned this through playing a deep stack a little too 'aggressively', but actually rather carelessly.
Heres my new-found approach to playing deep stack...
I will play more aggressively, playing those hands that I like... suited middle connectors through off-suit mid-high connectors and the occaisional low end connectors. My bet size increases, BUT, I will bet the same large (in relation to both pot odds and stack size) bets with both rags and nuts, showing my pocket in both instances. What I find then is that my opponents do not know what I am playing with because they have seen the same bets with all different kinds of hands. After a few shows like this, they tend to get very much more cautios and fold alot against me in the later rounds.
Of course I make sure that post-flop my actions soorespond to whats on the board. i.e. if there is a possible flush draw or straight draw, etc....
Did that make sense?
