After talking to Lane and his rival for the job, Spanish Economy Minister Luis De Guindos, in an informal hearing "the majority of the political groups considered Governor Lane's performance more convincing", Committee on Economic and Monetary Affairs chairman Roberto Gualtieri said.
"Some groups expressed reservations for Minister De Guindos' appointment," he added in a statement.
Eurozone finance ministers are scheduled on Monday to pick their favourite to succeed Portugal's Vitor Constancio, whose eight-year mandate expires in May, as the ECB's number two.
The final decision will be taken on March 22 at an EU summit after consultations with the European Parliament and the ECB's Governing Council.
Luis de Guindos said this month he was "convinced" he will have enough support to clinch the post after Madrid officially nominated him for the job.
Constancio's replacement is being watched closely in European capitals as it is the first in a series of changes due at the top of the ECB over the coming two years, including the post of the chief of the bank currently held by Italian Mario Draghi.
The committee Thursday also said it "regrets that no female candidates have been put forward, as requested, and calls for a more gender balanced representation in the ECB".
Only one woman currently sits on the ECB's ruling body, German national Sabine Lautenschlaeger.
