The Belgium striker, on a season-long loan from Chelsea, has scored just once in his last nine Premier League appearances.
In his nine league outings before that, the 20-year-old had netted eight times - and he believes a change in his role under Roberto Martinez is the cause for the goals drying up.
Speaking to Belgian newspaper Het Nieuwsblad, Lukaku said: "It looks like I'm becoming more and more of a target-man.
"That's not my best role. I want to make runs and look for the space in behind defenders.
"Hopefully, that will change. I'll have to make sure I play better in the next games, and create more chances for myself."
Lukaku set up Kevin Mirallas' goal in the 1-1 draw at West Brom on Monday night, and he added: "I was happy that Kevin scored - it was an extra assist for me. That's my fifth one, so I'm doing well. But in the first place, I'm a striker. I want to score goals."
Lukaku also sported a new look in that game at The Hawthorns, having had his dreadlocks cut off.
"Most people say I look younger due to my new haircut," he said. "I'm 20, so I'm a young man. I don't have a reason to change, but it was about time.
"My hair needs to grow a little bit and I'll have to return to the hairdresser a few times. Then you'll see the definite result!"
Up next for Everton is an FA Cup fourth-round tie at League One's bottom club Stevenage, with the Merseyside derby against Liverpool at Anfield following three days later.
The more I hear Lukaku speaking the less interested i am in hoping he becomes a permanent addition to the Martinez revolution. Dont know what he means by a target man?? Everton havent been using him as such, we're passing better than we ever did under Moyes and while some long balls are inevitable, most of his goals have come through passing play that Barcelona fans would appreciate. @bobsy nice bit of trolling there man, havent got a clue what it means though, and no dont care.- boggo
