Line up with the top right corner of the ground strip.

Aim in the middle between the T and the K. Bring your crosshair down until you reach the second black strip going horizontally on Bank (if tree branches are in the way, the strip can be easily seen coming from the right). Whole-screen X-crosshair might be useful with this lineup (https://www.csgonades.com/blog/smoke-align-crosshair). Left-click to throw.

Smoke will land at the end of long. Caution: CTs can do a jump spot to see the Ts long. They can, however, be heard doing this.

Smoke offers a one-way for Ts peeking through the left side of the smoke.
