How am i supposed to write eigenkets of an operator whose matrix is given to me given that the two ket vectors form an orthonormal basis .

Eigenkets is just the "quantum mechanical" name for eigenvectors. So you find the eigenvectors, and then make them orthonormal (e.g. apply the Gram-Schmidt orthonormalisation process)
