How to pressure Yun on his wake-up - What you need to know:
I was in the lab earlier, and I was experimenting a bit with the Rog vs. Yun wake-up game. Yun has some decent wake-up options (upkicks and a good backdash), so you’ll still have to guess correctly and take some calculated risks if you want to go on the offense against him during his wake-up. In any case, it’s always better to know what your opponent’s options are, and how to beat them, hence this post. 
(Only options that have startup invincibility are listed here. Everything not listed loses to wake-up meaties).
Non-ex Dragon Kicks:
Yun’s non-ex dragon kicks have slow startup and are reasonably easy to safe jump. Here’s what you need to know about them:
Move properties with reference to the Balrog matchup:
-LK is the fastest, but Rog can duck under it. It will sometimes cross over (and thus remove your back charge, making heavy damage punishes harder) if you’re crouching point blank.
-HK is the slowest version. Rog can not duck under the first hit, but the second hit will whiff if you’re crouching. Watch out as this move will usually carry Yun quite a long distance away, so if you’re not expecting it, it can be difficult to punish.
-MK is somewhere in between, but unlike the other two it doesn’t appear to have invincible startup, and it loses to wake up meaties. You probably won’t see it that much.
-They can’t be FADCed.
Safe offense options:
If you expect a non-ex dragon kick reversal, use a safe jump or safe meaty jab setup and block high afterwards. If you block high, LK version won’t cross over so it should be easier to do a higher damage punish combo (ex RU loop). It will also block the 2nd hit of the HK dragon kick, which should push you back a bit farther, making it easier to punish. Against a meterless Yun, meaty safe jumps/jabs will beat all his options except blocking and back dash.
Punishment options against HK dragon kick:
-HK dragon kick is punishable on block with auto-correct ultra or super. If you have no meter, you can walk in and do: cs. mp, cr. lp, cr. lk/mp xx (combo-ender of choice).
EX Dragon Kicks:
Yun’s ex dragon kick starts up in 4 frames and has invincibility. While theoretically it can be safe jumped, it’s quite difficult to do in practice because Rog lacks a consistent 4 frame safe jump setup.
Offense options:
As mentioned above, you can safe jump Yun’s EX Dragon Kicks, but doing so consistently is difficult unless you’re a Jedi or otherwise have God-like timing. So here are some other alternatives:
-delayed throw OS: Do a delayed throw on his wake-up. This should beat ex dragon kick (you’ll block it), blocking (you’ll throw him), and should keep you safe from wake up normal throws (you’ll tech them). This setup will lose to non-ex dragon kicks and Yun’s command grab however.
-cr. jab crouch tech OS: Same as above, but instead of a throw you do a cr. jab plinked with lk.
Back Dash:
Yun’s back dash can be OSed by buffering a sweep into your safe jump or safe meaty jab. You have to read the back dash correctly however, as non-ex dragon kicks will blow the OS up.
