I remember the hands separately, but I look at the chord as one, if that makes any sense.
I remember the right hand chord in relation to the left, for example, dom7 a whole step up, or minor a whole step up. I stack chords most of the time, so my left hand plays a diatonic 7th and the right hand will play some chord with the melody at the top, usually a normal major or minor chord.
I also use T-Block's method.
