4 day split, 2 days focused on bench, 2 days focused on squat/DL. You can start with early in the week focusing on higher intensity work in the 1-3 range, and later in the week focused on higher volume work in the 4-8 range with more sets. A good deal of assistance/supplemental work on all 4 days.
Later on you'll need to train with longer blocks of higher volume training followed by shorter blocks of higher intensity/lower volume stuff.
Pretty standard intermediate to early advanced stuff conceptually. The devil is in the details and I know very little about you so I can't give you much more than that.
