Just a general idea here:
1. Superset dips with pullups, varying grip on both
2. Superset some sort of chest press with some sort of row, again varying grip
3. Superset some sort of leg press (sqaut, lunge, press machine etc) with some sort of deadlift.
Throw in some shoulders on days one or two. Calves wherever. Abs where you feel like it.
Varying the grips (getting closer grips) as suggested for days one and two will help work your arms but throw some isolation stuff in there if you want.
I give such a vague outline because you said you were getting bored with your old routine. This would give you some freedom - experiment with different exercies and see what works best. Plus many people see results with the variation.
