If the 3579/793(13) voicings are too dense, you can always drop the second or 3rd note from the top down an octave, and split the notes between the two hands.
Another easy way is to play the 3rd and 7th in the left hand, and any scale tone from the implied tonal centre (ie: Cmaj if ii is D-7 or V is G7). The only limitations: don't play the chordal 4th on the dominant or the tonic (ie: C on G7 or F on Cmaj7), because it destroys the V-I resolution, and just sounds bad.
