Traped in the nether- part 1 series 2 (building our base)

When we got home we started to build a weat farm when it was done it had melons,pumpkins and weat growing.Then we built a house with a enchantment room,kitchen and a smelting room.Once that was done we tamed some horses and went dungeon hunting we found one in it's chests there was too diamond horse armor sets and saddles.So we built a stable to put our horses in and our base was nearly set up but now we needed nether wart and blaze rods what do we now?
