How do I do this in Lyx?

You could use an array in a regular equation environment.  Then you
have more control over alignment of each column in the array.

One possibility: use the AMS Alignat environment with *four* columns and
leave the third column empty.  So, using | to denote column breaks:

a | S | | b
c | T | | d
