Born in Bilbao, Biscay, Basque Country, Alaña graduated from Athletic Bilbao's youth system at Lezama, and made his senior debut with the farm team in 1999–2000, in Tercera División. He was promoted to the reserves in July 2000, going on to compete in three Segunda División B seasons with the side before being released in June 2003.
In the summer of 2003, Alaña joined neighbouring club SD Eibar. He appeared in his first game as a professional on 14 September 2003, starting in a 0–0 home draw against Córdoba CF for the Segunda División championship.
Alaña scored his first professional goal on 7 February 2004, netting his team's in a 1–1 home draw against Recreativo de Huelva. He played 26 matches during the campaign, helping to a tenth-place finish in the second level.
After appearing in an average of roughly 22 games per year (he also missed most of 2005–06 due to injury), Alaña was released by the Armeros on 24 June 2009. He subsequently resumed his career mostly in division three, representing Polideportivo Ejido, Deportivo Alavés, SD Amorebieta and SD Leioa; he also helped the last club win promotion to that tier in 2014.
In July 2017, one year after working as a coach with Athletic's youths, Alaña was appointed head coach of their third team Basconia. After a poor season in which they barely escaped relegation, he was replaced in the role by Aritz Solabarrieta but remained with the club, taking charge of the Cadete B (under-15) squad.
