Work backwards from meet day. Deload the week of the meet do very light weight and practice commands. Two weeks out work up to heavy triples on each lift, these are your openers, three weeks out work up to heavy doubles, these are your second attempts. A month out you should be hitting your peak volume and also dropping most or all accessories. Before that you'd pretty much be mostly training normally, although comp specific in terms of the lifts. Do them as you'd do them at the meet.
