Okay, I've looked into it.  'Sit' and 'Set' both come from the IE root
*sed.  'Sit' comes from a simple y-stem PG *sitjan>OE sittan > MnE sit.
However, 'set' comes from the same root, plus the IE causative suffix
'*-eyo'(cf. Sanskrit '-aya').  This suffix caused ablaut, creating the
PIE stem *sodeyo-.  In Germanic, *ei~*ey>*i ~*j was a  sound shift, so
we got PG *satjan, which, in West and North germanic, caused umlaut, so
NWG *settan>OE settan>set.  Roughly.

The same goes for 'lie'.  It comes, evidently enough, from the IE root
'*legh', undergoing the same sound shifts:

*leghyo->*ligjan>licgan>lie
*logheyo->*lagjan>lecgan>lay
