My 6 year old daughter gets ready for bed and then must stay quietly in her room, but not in bed, until she is ready to fall asleep. She is not one to go right to sleep, so this is what works for us...
She is allowed to look at books, do puzzles, color with crayons(nothing messy) or play her leapster. It works well. She knows she needs to stay in her room. Then when she is ready to be tucked in she lets us know and then goes right to sleep. You can't really force someone to go to sleep. This takes away the battle and stress and you can go about your night. Should she not stay quietly in her room, we threaten to take something away. Like a treat for the next day.
