| I claim to be no expert, but the way I got into substitutions all started with V-I's. They are the easiest change to substitute over and a great place to start, then move onto the others mentioned... then create your own!!!! Substituting a chord onto a V chord in a V-I is a very bebop thing to do and was as far as many of the great beboppers had to ever go in their music to make them sound masterful. My first one is the diminished:
Lets say we are in C and plaing on "rhythm changes"
so the basic progression in I - VI - ii - V repeated.
we'll start with putting a diminshed chord on the V and in this case the V will be G7. If we think "raise the root by half" and then play diminished on that we will play G# B D F. this is like Playing a b9 on the V and creates a great tention to the G in the next chord (C). another very common bebop phrase is to surround the root of the V and then resolve it on the I... i.e playing G# F# - G or more comlicated surroundings of these, such as B D F Ab F F# G B D F D D# E ... please note this is starting line 3 of the stave and the highest note is the Ab... one legger above the stave.
This basic b9 principle can also be applied to the VI chord as VI - ii is also a V - I so you could play A# diminished.
This b9 substitution is the most common in the be-bop language.
Another substitution you could have on the V would be a #5 or augmented.
On V (G7) you could play G B D# G. the D# resovles nicely to the E in the I chord and this is a VERY Clarke Terry sound. heres a quick lick to play with, again in the same range as above: B D# G F D# E G.
After you have fully explored all these in all keys you can go on to looking at putting the tritone on the V and then into some very crazy substitutions, but these two and the tritone are all you really need to play some good fast boppin' jazz.
Good luck with your substitutions and remember, get one substitution down before you explore the next, its always good to feel so comfortable with one that u you think about it anymore, it just comes out from under your fingers. It takes time, but it pays off!
