Depending on how many kids you have and how much equipment you have, you may be able to do something like this. If you don't have all the equipment, you can modify.
We divide our team into four groups of four or five. Each group starts either at the main field, playing defense (two groups) or hitting in the cage down the left field line with our hitting coach.
We set up an L-screen, a "half apple" batting cage on the main field, a screen @ first, second and one in short center field for someone working the bucket so balls don't have to come back into the coach throwing.
We do a graded BP, so each hitter has to get down 2 bunts and execute two hit and runs. For each one they fail, they lose a swing out of eight. It is entirely possible and it has happened that someone will never get past the hit and run before they run out of swings, but it puts the emphasis on these aspects.
Between pitches, we have a coach hitting fungos from behind the 2B screen to our outfielders. Mostly they are working on angles to balls down the line and in the gap or going back on balls. We also have a coach and a player in the hitting group hitting fungos to the infielders between plays. Each ball live off the bat is played either to first or as a double play.
It is critical that your fungo hitters, especially the ones hitting to the infielders stagger their ground balls with your pitches to home. It takes a bit to get the rhythm down, but we have found this to be very effective for getting swings in and working other aspects of the game.
