Legolas will ride back to Lake-town after Smaug's demise, note that he's dead and the town has been demolished, and ride home to tell his father the news. That's when Thranduil will march on Erebor.
If I have the timing correct, Smaug leaves Erebor around the same time Legolas sets off after Bolg. So he'll either see Smaug in flight and get back before he's killed or will get back after he's killed. Either way, he has news for Dad--the dragon is dead! So then he rides home (hopefully without Tauriel) to fill his father in and they set out for Erebor. (Of course en route, Bard asks Thranduil for aid and he complies before they all--elves and men--continue on to Erebor.)
"I wouldn't mind Legolas aborting his chase after Bolg because he realizes Laketown needs protection and aid from the orcs (not to mention a dragon bearing down on them) and riding hard for Mirkwood to tell his father the men of the lake need help."
Tho I don't know if Thranduil would be THAT eager to assist men, as someone who as seen ages pass - this is a really interesting question? Personally I don't think Thranduil would care, really, if Laketown got torched, BUT Tauriel is there. So assuming Legolas sees the dragon in the sky, would he not turn all the way around to help her? And Thranduil just knows the dragon is on the move, and then realizes Legolas and Tauriel are gone, and that's what gets Thranduil into things?
Most of all, I didn't want Legolas to end up at Dol Guldur, which to me is stretching things re having Legolas in every battle.
