England played with Vardy and Kane up top and skipper Wayne Rooney in the number 10 role at the tip of a midfield diamond, but both front men found themselves on the flanks too often.
"We played with split strikers. If you play with them both through the middle with (Wayne) Rooney central as well you can't defend the wide areas," Hodgson said.
"There were some moments where you might be right and Kane and Vardy were a little too wide but their job is to split and come together at the right times," he added.
"If you play with a man in behind them, you have to make sure he has space in which to run."
England beat Australia 2-1 in a friendly in Sunderland last week, following up on their 2-1 win over fellow Euro 2016 finalists Turkey in May.
"I'm not prepared to accept that we didn't play well," Hodgson added. "I'm very pleased with three wins, we never looked like conceding a goal."
England, who have been drawn in Group B for the 24-team tournament, open their campaign against Russia on June 11 before taking on Wales and Slovakia.
