I always do 6x 1 day of writing + 1 day of recording (releasing singles when recorded) then 1 day of recording an album with 6 singles, 0 songs followed by 1 day of promoting and 1 day of gigging. I don't know if it is the best way, but it is working for me ;)
And definitely don't forget to put money in the bank; it doesn't make much money, since you will be taxed for richness (19m a day for me), but after a while it should cover your bands wages.
