This may not be what you are looking for but....
Nothing will beat a few minutes of long tones, scales and arpeggios for getting you into shape. Try this: 5 minutes long tones, 10 minutes of scales/arpgeggios (a different key each day to keep you from getting bored with routine), and then the rest of the time (15-45 minutes according to your timeframe above) playing songs you want to play, perhaps the Aebersold books. And play with a group (wind or jazz ensemble, combo, whatever) to have fun playing music with other musicians.
