Compute elements of n-torsion group of elliptic curve over finite field

Suppose Fq is a prime field and E/Fq is an elliptic curve over that field with order k=n... and assume that E has embedding degree l. Then the n-torsion group of E is in Fql. Now assume that n and l are reasonably small, such that the n-torsion group contains only a few elements and can be listed.

How can I compute that group and list the elements?
