There is no point in attacking empty military targets in Israel, because Israeli military is well prepared for such attacks.
To make Israel feel pain and regret its decision to strike Iran, to avenge the deceased generals and satisfy Iranian people, to establish deterrence and for going into History as a winner, Iran should attack major economic targets in Israel.
At least fully destroy Rutenberg powerplant, Intel semiconductor fabrication facility that costs 25bln$ and Bazan group petrochemical complex (the largest in Israel).
This will be a huge blow to Israel and send a message to Americans not to mess with Iran because Abqaiq in Saudi Arabia and the Strait of Hormuz are at Iran's mercy.
In response to such attack Israel will attack key Iranian powerplants and Abadan oil refinery, but this is war and you can't get out of it and win without some sacrifices.
