I'm trying to reproduce this notation in LaTex but to no avail.

This means $e_j$ has the value of $0$ in all other coordinates except for the j-th one.

I can only do the part without $(j)$: $e_j :=(0, ldots, 0,1,0, ldots, 0) in K^m$

Please shed me some light! Thank you so much!

Here's a solution which employs the amssymb and mathtools packages.

If you would like to push the (j) term a bit lower than in the picture shown above, simply change 1 to 1mathstrut.

Let $minmathbbN^times$. For $j=1,dots,m$ define
