The one I use for my Kinetic Defender (and should work equally well for my Rad/Kin Corruptor if I ever level her) is the following in a text file:
NUMPADx "+ unselect$$team_select_x$$powexec_name Speed Boost"
(where x is replaced by numbers 1 thru 8 accordingly)
The + at the start means that it might occasionally exceute twice, but you should only have to press and release the NUMPAD button to get it to fire off the power.
I use this for Speed boost (CTRL+NUMPADx), Increase Density (ALT+NUMPADx) and for Aid Other (SHIFT+NUMPADx)
Hope these help.

I did it via the Option > Controls menu. Less fancy than Binds but it was far easier to set up.
I set the Numpad numbers to select team members, Numpad 0 is Speed Boost (actually just "Fire Slot number 7" where SB is), Numpad. is Increase Density (slot 8), Numpad enter is Transfusion (the healing one, I get them mixed up: Slot0 anyway) and bounces off their target. Finally Numpad+ is Aid Other (which I have for patching up Blasters and other melee-fearing teamies).
CTRL+NUMPAD1 "+ unselect$$team_select 1$$powexec_name Speed Boost"
CTRL+NUMPAD2 "+ unselect$$team_select 2$$powexec_name Speed Boost"
CTRL+NUMPAD3 "+ unselect$$team_select 3$$powexec_name Speed Boost"
CTRL+NUMPAD4 "+ unselect$$team_select 4$$powexec_name Speed Boost"
CTRL+NUMPAD5 "+ unselect$$team_select 5$$powexec_name Speed Boost"
CTRL+NUMPAD6 "+ unselect$$team_select 6$$powexec_name Speed Boost"
CTRL+NUMPAD7 "+ unselect$$team_select 7$$powexec_name Speed Boost"
CTRL+NUMPAD8 "+ unselect$$team_select 8$$powexec_name Speed Boost"
and
ALT+NUMPAD1 "+ unselect$$team_select 1$$powexec_name Increase Density"
ALT+NUMPAD2 "+ unselect$$team_select 2$$powexec_name Increase Density"
ALT+NUMPAD3 "+ unselect$$team_select 3$$powexec_name Increase Density"
ALT+NUMPAD4 "+ unselect$$team_select 4$$powexec_name Increase Density"
ALT+NUMPAD5 "+ unselect$$team_select 5$$powexec_name Increase Density"
ALT+NUMPAD6 "+ unselect$$team_select 6$$powexec_name Increase Density"
ALT+NUMPAD7 "+ unselect$$team_select 7$$powexec_name Increase Density"
ALT+NUMPAD8 "+ unselect$$team_select 8$$powexec_name Increase Density"
Sorry - but I don;t know any other way to put that on the forum.
Apologies for the time taken to reply - topic notifications were turned off. 
I haven't included the rest of teh text file, where most of the kinetics powers are bound to the NUMPAD keys, letting me move and fire off blasts (occasionally! ) with my left hand, and hit all the buffs/heals with the other

Stealing Dax_s layout above me I'll throw my method out too, the way I should have set it up. Let me know if the keys or powernames are wrong, I don't have the game to test on at the mo.
NUMPAD1 "+ unselect$$team_select 1"
NUMPAD2 "+ unselect$$team_select 2"
NUMPAD3 "+ unselect$$team_select 3"
NUMPAD4 "+ unselect$$team_select 4"
NUMPAD5 "+ unselect$$team_select 5"
NUMPAD6 "+ unselect$$team_select 6"
NUMPAD7 "+ unselect$$team_select 7"
NUMPAD8 "+ unselect$$team_select 8"
NUMPAD0 "+ powexec_name Speed Boost"
NUMPAD. "+ powexec_name Increase Density"
NUMPAD+ "+ powexec_name Aid Other"
NUMPADENTER "+ powexec_name Transfusion"
^ I'm pretty uncertain on this last one btw
Hey guys. I need an easy bind for Speed Boost. Is it possible to make something like this:
(imagine a team of 8 members)
Numpad1 - Speed Boosts Player1 of the team
Numpad2 - Speed Boosts Player2 ...
...
Numpad8 - Speed Boosts Player8
Cheers
