Just off the top of my head.
cr lk, cr lp, cr hp, special. (anytime I say special you can use hado, srk, or tatsu, urually srk is preferred)
cr lk, cr lp, hp srk
cr mk xxx hadouken (use this often as a poke during the footsies game)
f + hp, srk
f + hp, s. mk, srk
f + hp, cr lp, cr hp, tatsu
Those last 2 are a little harder. For sure get the f+hp to srk down though.
Anytime they are cornered do something that leads into ex tatsu and then connect ultra.
Any lp srk into super.
any combo leading into srk, fadc, ultra
cr lk, cr lp, cr mp, hadouken or srk (only use a tatsu if you know they were standing or after a s hp or cr hp. If you dont do that and they are crouching the tatsu will whiff)
cr mp, cr hp, special
That’s pretty good to get you started.
Another very good damage wise is anything in the corner that ends with ex tatsu, ex hado, ex tatsu. For example jumping hk, cr hp, ex tatsu, ex hado, ex tatsu does the same amount of damage as a combo that uses the super. So you can get the super damage with only 3 bars.
