OK, so LV won't die till book #7, but let's have some fun suggesting 
fatal mistakes.

IDEA 1) NORBERT HELPS
Norbert the dragon returns and becomes the envy of any wizard that 
has heard of even 1 of the 12 uses of Dragon's blood.

A dozen DE stupify him to draw the blood of an alive dragon 
(fresher).

After taking some scales and other potions sdditives, LV standing 
triumphantly over Norbert makes the most basic blunder.
"Never Tickle a Sleeping Dragon" (Hogwarts school moto)

Norbert scrathes the itch in his sleep and knocks LV asunder. 
Someone (Harry?) from OOTP is handy to finish him off.

IDEA 2) TRANSFIGURATION SPELL
Again Harry is hiding behind stones (like in GOF tombstones) but 
instead of using AK as LV is trying, he aims above LV's head at some 
object (a leaf?) and transfigures that into a fridge, Dudley or an 
equally large heavy item to turn LV into roadkill.

IDEA 3) COS TUNNEL
Salazar Slytherin dug the Chamber of Secrets to came and go as he 
pleased. one tunnel leads underneath Hogsmede and can only be 
accessed by knowing where to apparate to exactly. Any error 
apparates you into your own grave.

OOPS, a loveable clumbsey character caved in the tunnel just before 
LV tries to use it

PS. Dear JKR,
feel free to use any of those scenarios
